Hi Akash, Thank you for the patch! Yet something to improve: [auto build test ERROR on tty/tty-testing] [also build test ERROR on spi/for-next wsa/i2c/for-next usb/usb-testing driver-core/driver-core-testing linus/master v5.7-rc6] [cannot apply to next-20200522] [if your patch is applied to the wrong git tree, please drop us a note to help improve the system. BTW, we also suggest to use '--base' option to specify the base tree in git format-patch, please see https://stackoverflow.com/a/37406982] url: https://github.com/0day-ci/linux/commits/Akash-Asthana/Add-interconnect-support-to-QSPI-and-QUP-drivers/20200521-163523 base: https://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty.git tty-testing config: x86_64-randconfig-r023-20200521 (attached as .config) compiler: clang version 11.0.0 (https://github.com/llvm/llvm-project 3393cc4cebf9969db94dc424b7a2b6195589c33b) reproduce (this is a W=1 build): wget https://raw.githubusercontent.com/intel/lkp-tests/master/sbin/make.cross -O ~/bin/make.cross chmod +x ~/bin/make.cross # install x86_64 cross compiling tool for clang build # apt-get install binutils-x86-64-linux-gnu # save the attached .config to linux build tree COMPILER_INSTALL_PATH=$HOME/0day COMPILER=clang make.cross ARCH=x86_64 If you fix the issue, kindly add following tag as appropriate Reported-by: kbuild test robot All error/warnings (new ones prefixed by >>, old ones prefixed by <<): drivers/soc/qcom/qcom-geni-se.c:739:27: error: implicit declaration of function 'devm_of_icc_get' [-Werror,-Wimplicit-function-declaration] se->icc_paths[i].path = devm_of_icc_get(se->dev, icc_names[i]); ^ drivers/soc/qcom/qcom-geni-se.c:739:27: note: did you mean 'of_icc_get'? include/linux/interconnect.h:30:18: note: 'of_icc_get' declared here struct icc_path *of_icc_get(struct device *dev, const char *name); ^ drivers/soc/qcom/qcom-geni-se.c:739:25: warning: incompatible integer to pointer conversion assigning to 'struct icc_path *' from 'int' [-Wint-conversion] se->icc_paths[i].path = devm_of_icc_get(se->dev, icc_names[i]); ^ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ drivers/soc/qcom/qcom-geni-se.c:790:9: error: implicit declaration of function 'icc_enable' [-Werror,-Wimplicit-function-declaration] ret = icc_enable(se->icc_paths[i].path); ^ drivers/soc/qcom/qcom-geni-se.c:807:9: error: implicit declaration of function 'icc_disable' [-Werror,-Wimplicit-function-declaration] ret = icc_disable(se->icc_paths[i].path); ^ >> drivers/soc/qcom/qcom-geni-se.c:829:11: error: implicit declaration of function 'of_get_next_parent' [-Werror,-Wimplicit-function-declaration] parent = of_get_next_parent(wrapper->dev->of_node); ^ >> drivers/soc/qcom/qcom-geni-se.c:829:9: warning: incompatible integer to pointer conversion assigning to 'struct device_node *' from 'int' [-Wint-conversion] parent = of_get_next_parent(wrapper->dev->of_node); ^ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ drivers/soc/qcom/qcom-geni-se.c:883:26: error: implicit declaration of function 'devm_of_icc_get' [-Werror,-Wimplicit-function-declaration] wrapper->to_core.path = devm_of_icc_get(dev, "qup-core"); ^ drivers/soc/qcom/qcom-geni-se.c:883:24: warning: incompatible integer to pointer conversion assigning to 'struct icc_path *' from 'int' [-Wint-conversion] wrapper->to_core.path = devm_of_icc_get(dev, "qup-core"); ^ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 3 warnings and 5 errors generated. vim +/of_get_next_parent +829 drivers/soc/qcom/qcom-geni-se.c 818 819 void geni_remove_earlycon_icc_vote(void) 820 { 821 struct geni_wrapper *wrapper; 822 struct device_node *parent; 823 struct device_node *child; 824 825 if (!earlycon_wrapper) 826 return; 827 828 wrapper = earlycon_wrapper; > 829 parent = of_get_next_parent(wrapper->dev->of_node); 830 for_each_child_of_node(parent, child) { 831 if (!of_device_is_compatible(child, "qcom,geni-se-qup")) 832 continue; 833 wrapper = platform_get_drvdata(of_find_device_by_node(child)); 834 icc_put(wrapper->to_core.path); 835 wrapper->to_core.path = NULL; 836 837 } 838 of_node_put(parent); 839 840 earlycon_wrapper = NULL; 841 } 842 EXPORT_SYMBOL(geni_remove_earlycon_icc_vote); 843 --- 0-DAY CI Kernel Test Service, Intel Corporation https://lists.01.org/hyperkitty/list/kbuild-all@lists.01.org
